Here we go - another audiophile who claims that having less than $1000 of audio equipment means a dedicated sound card will provide no discernable difference in audio quality. Let me guess you have a
Wilson Audio setup in your living room, won't listen to anything less than Senns HD800 on your portable media player and you paid $6000 for the Bang & Olufsen Audi sound system upgrade?
I am using X-Fi, not Xonar. I invited my friends over and toggled between onboard sound and my dedicated sound card. They all couldn't believe how much better my X-Fi was once I enabled the Crystaliser and Surround Xpand mode. My computer speakers are nothing special and they sound a magnitude of times better with the X-Fi.
The Xonar allows you to tweak
27 EQ and Bass settings. The FlexBass feature allows for bass adjustments from 50HZ to 250HZ for those looking for more bass impact. You say this is useless?
You want scientific testing? Here you go:

"The goal with the ASUS Xonar DX is to offer better audio quality than common integrated audio and these metrics show that when it comes to overall quality, the Xonar DX is definitely a huge improvement." - HotHardware
The Xonar DX blows away onboard audio in every parameter.
Ok how about this, let the OP order the Xonar for $70. Let him test it back to back with onboard sound and tell us if he finds any sound differences in favour of the Xonar. If he doesn't find
any of these:
1) Much improved bass response/quality of bass (i.e., vs. muddled bass on integrated);
2) Much improved clarity / additional detail of sound in sound tracks;
3) Much improved 'fullness' to the sound;
4) He'll be able to turn up the sound volume to much higher levels while still retaining clarity / maintaining lower distortion;
5) Much superior spatial orientation in games as well as with DVDs.
I'll send you $100. And if he does you'll send me $100.
I am willing to take this bet because I know that any decent dedicated sound card is far superior to onboard sound and the sound improvement will show even in a $150 set of speakers. Even objective testing with Rightmark Audio Analyzer 6.0.6 showed this.
There are plenty of people who report that a dedicated Xonar sound card makes a
huge difference even on sub $250 speakers (which according to you is a 'laughable' set of speakers).
"The sound quality is incredible, when used with headphones costing upwards of $50 US you really notice the difference. It is indeed like magic never can I go back to onboard sound, the detail and bass you experience is phenomenal"
52% of Newegg reviewers gave it
5/5 stars. All 132 of these people are wrong?
Plug in a DVD movie or game which supports surround sound signals. Most current on-board audio cards are unable to generate 5.1 or 7.1 signals of their own from a stereo signal, unlike a comparable dedicated card.
